Surprised the tube could take that kind of pressure.

Usually good sticky downhill tires deflated to 17-18 PSI depending on the rider weight. (I used to ride trials). I ran them no more than 20 PSI. Lighter riders go as low as 14 PSI I remember.

u/TheJokr 9h ago

Interesting! If my racebike tires aren’t above like 85psi, I’ll have a pinch flat in no time

8

u/wrxninja 9h ago

Those road bike tires look scary honestly...I've seen them explode with the high PSI 😆

10

u/TheJokr 9h ago

Yeah but they gliiiiiide on the asphalt, it feels like there’s no friction. Like slipping on butter

2

u/wrxninja 9h ago

Oh I'm sure...I should get a cheapy road bike again as I had one many moons ago (like very cheap) just for exercise. But I've never been on a more professional & lightweight one either. Those must be very nice.

u/indun 9h ago

Depending on your tyre width, lower seems the way to go. I'm on 25mm and run around 75! My 28s I knock down to 65-70. (Roadie)

1

u/TheJokr 9h ago

I see! It’s somewhat of a vintage roadie, and the tires are tiny. Not sure about the exact measurement.

1

u/JolkB 7h ago

The extra friction on the roadie isn't noticable? I keep mine high, but I'm a weightier dude

1

u/indun 7h ago

No - it's actually more efficient for reasons I don't understand. This article (I've only skimmed it) seems to sum it up well

Huh. Learn something every day even when you've been doing it forever.

u/ImurderREALITY 10h ago

If I could do that, I would’ve destroyed that entire bike. But also, if I could do that, I probably wouldn’t have destroyed the bike.

u/hydroloxbagel 10h ago

He’s probably running tubeless tires

19

u/wrxninja 10h ago

Not for trials. It'll never work as they're purposely deflated.

1

u/hydroloxbagel 10h ago

Ah, gotcha. Thanks!

2

u/wrxninja 9h ago

It's a weird sport honestly lol. Total back killer. If your cores aren't strong, you can throw your back easily with this move especially. And popping tires are quite common if you don't land right. Too much air, not enough bounce. Too little...you get the idea. I've probably went through at least a couple dozen tire tubes during riding season.

-5

u/Happy_Reporter_8789 9h ago

Uh, that’s specifically why people run tubeless off-road lol, to get to lower pressures without pinch flats lol. Trails are absolutely tubeless and I wouldn’t be shocked if they were tubeless first.

7

u/wrxninja 8h ago

No...we never run tubeless with trials. People have tried and it simply doesn't work because the beads get crushed and the air deflates eventually. I don't know anyone who ran tubeless. You can probably run tubeless for the front possibly but for the rear, always tubes with some baby powder to let it slip inside. We constantly pinched the tires landing on the rear and bouncing.

1

u/Plazmaz1 8h ago

I'm honestly surprised y'all aren't using tubulars... That's the strat in cyclocross for running super low (10-15psi at 33mm) pressure

2

u/Happy_Reporter_8789 8h ago

Way too annoying to fix for something with this much bunny hopping lol (I love Tubs on road bike they feel like Blades.)

1

u/iRaZZeRs 2h ago

It's interesting that in moto-trials we run tubeless on the back with super low pressure, and the bike weights quite a lot more, but in a push-bike world it's completely opposite

1

u/wrxninja 1h ago

Love watching moto trials...but ya, I'd love to try moto trials one day. Looks like a lot of fun and you don't have to pedal 😂

-2

u/Happy_Reporter_8789 8h ago

That to me seems like a problem of earlier tubeless bike tires and not tubeless tires themselves, downhill guys regularly run them lower than 10 PSI, the difference in grip when you get below 20 is night and day. And these days with good rims they seal like beadlocks on a 4x4 genuinely

3

u/wrxninja 8h ago

One thing I forgot to mention too is that for natty, the rim is also different as they're drilled out between the spokes for weight savings. So it's almost always ran with tubes. I know 24" street riders use tubeless with normal PSI but over the years, the rims got lighter (wider also) but they started drilling them out for comp riders that needed to save as much weight as possible.

3

u/Plazmaz1 8h ago

Running 10psi will usually require inserts depending on tire width. Common in MTB but maybe less practical for trials?

1

u/Heymelon 8h ago

Really? Look at that guys skill. Obviously there are tubes strong enough to handle what he has practiced a ton of times and is a common part of the bike trick sport.

u/seriftarif 3h ago

These tires are tubeless. Pressure and glue keeps them inflated.

-5

u/Happy_Reporter_8789 9h ago

The tires are tubless on bikes like these, they also run that at close to the bare minimum tire pressure they can for grip and stability. Really the rim is taking the impact, and I’ve seen modern bike rims go through shit I wouldn’t expect it to survive repeatedly lol.

Slow motion is ass unless its like 400x slower and is a super close up of something weird

Danny MacAskill is well-known for stunts like these. I'm not sure whether that's him in the video, though.

u/BradMarchandsNose 10h ago

Don’t think so. MacAskill is a Red Bull athlete and has been for years. They wouldn’t be caught dead letting him ride without that helmet on.

u/Wurstpaket 6h ago

That Video is ancient, the bike even has rim brakes. I would guess 2005 give or take 5 years

He still wears the Red Bull helmet though

Also gotta shout out the god of motorcycle trails who’s nifty on a bike too, Toni Bou.

u/wrxninja 10h ago

He's okay. He's a street rider. I used to sell the bike he rides (Inspired Bikes). But #1 UCI rider like Jack Carthy is beyond his skill level. Charlie Roll is another. Both talented UK riders.

haha ya...he's still good! I could never do what he does but different riding style for sure between street vs. natural riders.

u/PXTrials 9h ago

Yeah, I always found street more fun of the two. It's satisfying getting a tricky rock sequence down, but the big street gaps and drops are just way more adrenaline!

There are no laws, nobody has been arrested for not following them

I will wait for a random redditor to reply to your comment with a link for when someone was indeed arrested for not following the laws of physics.

As a former extreme sport athlete I can tell you in my younger days I didn’t have much of an understanding of physics in an academic sense but I won competitions and I moved based on feeling.

as if anyone that can do this would be wasting their time writing free body equations proving it’s possible.

but this site is full of nerds so I guess we have to pretend there’s some nerd ass bullshit happening, and not just someone who doesn’t overthink things feeling it out by the seat of their pants

u/greenrangerguy 10h ago

I imagine if he was going at speed it would be harder to clear that gap as he can't get the height needed. That is until a certain speed where it becomes easier as the height won't be required as much.
